Description

  The present invention relates to a cooking apparatus for meat dishes such as steaks, and more particularly to a meat cooking apparatus for cooking without failure even by an unskilled cook in a restaurant or the like.

  There are many different ways to cook steaks, and the cooks pride in practicing their cooking methods. A chef at a high-end restaurant advises that the meat is constantly moving so that heat is evenly applied to the meat, that the meat surface is not damaged so that the juice does not come out, and that the surface condition is observed. Yes. However, there are also tips for being a chef at a high-end restaurant, and it goes without saying that the quality of cooking depends on the ability of the chef.

  Steak is not only served in high-end restaurants, but there are also popular restaurants that serve steaks to a large number of customers in a short time at a reasonable price. In such a store, in order to heat the meat in a short time, the meat is placed on an iron grill and heated from below by a charcoal grill or the like. However, charcoal fire is not easy to adjust the temperature, and the temperature change is large and the temperature distribution is not uniform. Therefore, the state of radiation, convection and heat conduction changes every moment. When such a heat source is used, it is very difficult to adjust the degree of baking (rare, medium, welldan) in the meat.

  In such a store, an unskilled cook may cook. In such a case, it should be possible to provide a large number of steaks in a short time without failure. In order to prevent such a cook from failing in cooking, it is important to minimize the temperature fluctuation of the heat source of the cooking apparatus and make the temperature distribution as uniform as possible.

  For this reason, in some restaurants, meat is placed on a plate made of lava, and the plate made of a single lava is uniformly heated to heat the meat slowly. Even in this case, it is still difficult to keep the temperature of the plate made of lava at a predetermined temperature according to the prior art, and it takes time for cooking, and it is difficult to provide a large amount of meat dishes.

  In Patent Document 1, when a stone plate is used, if there is a large amount of oil from the meat, the oil remains on the surface of the stone plate and a juicy baking cannot be obtained. Cleaning is not easy due to the need for cleaning.Further, grilled debris, etc. generated during grilled meat is deposited on a large stone plate, and when the cooking is continued, In order to solve the problem that it is difficult to remove and is not easy to clean, an exhaust passage is provided above the burner housed in the inner box to support the stone block holding container, A large number of stone masses are stored in the storage device, and the meat is heated by infrared rays emitted from the stone mass. At that time, excess oil falls individually from the small stone mass and can be stored in the deep dish-shaped storage device. A stone block roaster is disclosed.

  In addition, to shorten cooking time, some restaurants place meat on a horizontal bar grill, radiation from the lower charcoal fire, air convection, and heat conduction from the heated grill. The meat is heated directly. In this case, many lava fragments may be mixed in the charcoal fire. Lava fragments are intended to equalize the temporal variation of the temperature of the heat source charcoal fire and the spatial temperature distribution. Even if lava fragments are mixed in the heat source in this way, the problem of temperature change and temperature uniformity still remains, so for unskilled cooks, the degree of burning in meat (especially thick meat) The current situation is that it is not easy to adjust (rare, medium, welldan).

JP 2001-149229 A

  In a popular restaurant that provides steaks to a large number of customers in a short time at a reasonable price, an unskilled cook may cook meat dishes as described above. In such a field, with the conventional heating method, meat dishes may not be finished as intended by the cook due to temporal variations in temperature and spatial non-uniformity.

  In order to cook even a non-skilled cook with a certain quality, it is important to heat the meat to be cooked in a uniform temperature environment. Then, the 1st subject of this invention is providing the meat cooking apparatus from which the temperature of the environment which heats meat is as uniform as possible, and becomes a wide range.

  In the case of a meat cooking device having a structure in which liquid (oil or the like) flows out when meat is baked and stays above the burner, there is a possibility that the heat of the burner will ignite. The fire may change its temperature distribution and deviate from the designed uniform temperature distribution. When such a situation occurs, an unskilled cook may be forced to deal with it and may not be able to cook the meat to the set quality. Accordingly, another object of the present invention is to provide a cooking device that is less susceptible to ignition of a liquid (such as oil) that has flowed out of meat and that is easy to maintain.

  If you concentrate on cooking meat to the set quality, you may accidentally touch the hot part of the meat cooking device and burn yourself. Then, the further another subject of this invention is providing the meat cooking apparatus with the low temperature of the apparatus front surface which a cook tends to touch.

It is the infrared photographic image which showed the temperature distribution of the mounting part.

  Hereinafter, embodiments of a meat cooking apparatus according to the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the meat cooking apparatus according to the present invention includes a burner 1 and a radiating member 2 for converting heat generated by the flame F of the burner 1 into heat radiation.
The burner 1 is composed of a straight pipe 1a provided with gas blowing holes, and each burner 1 is formed by connecting two pipes 1a and 1a with a central pipe 1b as shown in FIG. The gas is supplied from a gas supply unit (not shown) to the gas supply port 1c connected to the central pipe 1b. Further, in this embodiment, each burner 1 has an “industrial” shape when the two pipes 1a, 1a and the central pipe 1b are viewed from above. Note that the number of pipes constituting the burner 1 is not limited to six shown in FIG. 1, and may be formed of, for example, four or two pipes. Furthermore, the shape of the pipe constituting the burner 1 is not limited to a linear shape, but may be other shapes. FIG. 2 (b) shows the burner 1 in a state of being housed inside the casing 7 of the meat cooking device.

  The radiating member 2 is disposed immediately above the burner 1 and in parallel therewith. The radiating member 2 has a structure in which a pair of main body radiating members 2a and 2a are connected to each other by an intermediate radiating member 2b. In other words, the burner 1 having a “K” shape when viewed from above is disposed so as to cover the radiation member 2 having a “K” shape when viewed from above. The radiating member 2 has a shape in which the upper width is narrow and the lower width is wide so that the liquid S dripping from the heated meat does not fall on the burner 1. For example, as shown in FIG. 1 or FIG. 2 (b), the cross section is formed of a metal bar, for example, SUS304.

  Moreover, the radiation member 2 is detachably latched by the radiation member latching | locking part 2c currently fixed to the inner wall of a cooking device, as shown in FIG.2 (b). Since the radiation member locking portion 2c is detachable, maintenance such as cleaning of the inside of the meat cooking apparatus such as the radiation member 2 and the burner 1 is easy. The radiating member 2 is heated not only by the heat of the burner 1 but also radiates radiation in all directions to make the temperature distribution uniform, and the liquid S dripping from the heated meat is shown in FIG. It also has a function of not falling on the burner 1.

  As shown in FIG. 1, a heat storage means support net 4 and a net cover plate 5 for supporting the heat storage means 3 are disposed on the burner 1 and the radiating member 2. FIG. 3 is a top view of the heat storage means support net 4 and the net cover plate 5. In the illustrated embodiment, the heat storage means support net 4 is composed of two nets 4a and 4a. In FIG. 3, the burner 1 is shown by a broken line below the heat storage means support net 4. The two mesh closing plates 5 and 5 are placed on the heat storage means support net 4 so as not to overlap the burner 1 in the central region of the heat storage means support net 4. As shown in FIG. 3, the lower burner 1 and the net closing plate 5 may partially overlap. The arrangement position of the mesh closing plate 5 is set as a part of the heat storage means supporting net 4 that becomes a particularly high temperature portion by the burner 1 arranged below, and the net closing plate 5 on which the mesh of the heat storage means supporting net 4 is placed. It serves to block the air and disperse the hot air from side to side. By providing the net-clamping plate 5 having such an action on the heat storage means support net 4, the temperature distribution of the heat storage means support net 4 is fairly uniform, and the range of the uniform temperature distribution covers a wide range. Become.

  When the burner 1 is composed of four pipes, the portion of the heat storage means support net 4 located above the middle portion of the pair of two pipes is a particularly high temperature portion. A sheet of netting plate 5 is placed. FIG. 4 conceptually illustrates the operation and effect of the net-capping plate 5 in this case. When the net-capping plate is not attached to the upper stage, the middle stage stores heat in the net-capping board 5 made of a rectangular plate-like body. When attached to the central region of the means supporting net 4, the lower stage has a through-hole 5a near the center of the plate surface and the net covering plate 5 made of a plate-like body formed wider in the vicinity of the center. It is the figure which each showed the case where it attached to the center area | region. In addition, the broken line in a figure shows the burner 1. FIG. As shown in the right figure showing the temperature distribution in each case, when the mesh closing plate is not attached, an ultra-high temperature part appears near the center of the heat storage means support net and the area of the hot part that can be cooked is narrow It has become a thing. When a mesh-clad plate made of a rectangular plate-like body is attached, the rise of hot air in the portion is suppressed by the mesh-clad plate, and the hot air is distributed to the left and right of the mesh-clad plate. The region of the high temperature part that is lost and can be cooked widens. When a screen-blocking plate made of a plate-like body that has a through-hole near the center of the plate surface and is formed wider near the center, a part of hot air flows from the through-hole formed near the center. Moreover, the hot air is dispersed farther toward the center by the netting plate formed wider toward the center, so that the super-high temperature part disappears and the region of the hot part where cooking can be performed becomes wider. As described above, the mesh closing plate 5 functions to disperse the hot air heated by the burner 1, and changes the width of the mesh closing plate, changes the shape as described above, or penetrates the plate surface. A temperature distribution that is easier for the user to use can be realized by opening the holes. Moreover, as shown in FIG. 5, it is good also as a plate-shaped body which has the downward bending piece 5b in a part of periphery of the netting board 5. As shown in FIG. In this case, the hot air is blocked by the bent piece 5b, and the flow of hot air in that direction can be restricted, and the strength of the netting plate is improved by forming the bent piece 5b. Can do.

  The heat storage means 3 is placed on the heat storage means support net 4 and the net cover 5 as shown in FIGS. The heat storage means 3 is a metal piece or a rock piece, preferably a lava piece. Further, as shown in FIG. 1, the heat storage means 3 are arranged in a single layer so as not to overlap each other and are evenly arranged on the heat storage means support net 4 and the net cover plate 5. As a result, the lower surfaces of all the metal pieces or rock pieces that are the heat storage means 3 come into contact with the heat storage means support net 4 and the net cover 5 and are heated evenly. Since the metal piece or rock piece which is the heat storage means 3 is evenly heated and heated up, radiant rays including infrared rays are evenly emitted from the surfaces thereof. Moreover, since the time change of temperature becomes slow with the heat capacity of a metal piece or a rock piece, cooking temperature does not change suddenly and cooking becomes easy.

  The heat storage means 3 arranged as shown in FIG. 6 and FIG. 7 is based on the heat convection heating directly heated by the combustion gas of the burner 1 and the contact with the heated heat storage means support net 4 and the net closing plate 5. Heated by heat conduction heating. Due to the action of the screen closing plate 5, the temperature distribution on the heat storage means support net 4 and the screen closing plate 5 is fairly uniform as described above, so that the heat storage means 3 also has a uniform temperature.

  After arranging the heat storage means 3 as shown in FIG. 7, the meat placing member 6 is mounted on the upper surface of the meat cooking apparatus as shown in FIG. The meat placing member 6 is preferably formed of a metal having a high thermal conductivity such as aluminum, copper, or iron in order to make the temperature distribution uniform. Further, the shape of the meat placing member 6 is preferably formed as a grid made of metal bars arranged in parallel as conceptually shown in FIG. 8 from the viewpoint of uniform temperature distribution and from the viewpoint of thermal efficiency. .

  The meat placing member 6 is heated by the heat convection heating directly heated by the combustion gas of the burner 1 and the contact with the heated heat storage means supporting net 4 and the net closing plate 5 so that the temperature distribution is fairly uniform. The heat storage means 3 is heated by heat radiation. As a result, the temperature distribution of the meat placing member 6 becomes uniform, and the meat N placed and cooked thereon is heated uniformly. At the same time, since the temperature change of the heat storage means 3 is small, the radiant heat does not fluctuate and the meat N is heated uniformly over time.

  A part of the liquid S such as gravy coming out of the heated meat N is burned by the heated heat storage means 3 below, but those not burned and other waste fall further down. As described above, the dropped liquid S or the like is blocked from dropping onto the burner 1 by the radiating member 2 and is accumulated in the residue receiver 11 (FIG. 1) provided below the burner 1. The residue receiver 11 is detachably attached to the lower part of the apparatus, and the residue is taken out before starting work. Since it is difficult for the waste receiver 11 to move a liquid containing a liquid in a wide flat container, it is preferable to use a structure of an assembly of small containers 11a and 11a divided into two or more because it is easy to handle.

  If a cook inadvertently touches the hot section of the meat cooker, it may burn. For this reason, it is necessary to always pay attention to the high temperature part, but this causes a problem that cooking tends to be sparse. In the present invention, as shown in FIG. 8, the front surface of the casing 7 that houses the burner 1, the heat storage means 3, etc. of the meat cooking device is disposed with a space 8 a between the outer wall of the casing 7. It is covered with a heat shielding plate 8. Further, in the embodiment of FIG. 8, cocks 9 for operating the apparatus are arranged at the lower front portion of the housing 7.

  Since the meat cooking apparatus according to the present invention has the above-described configuration, the temperature of the meat placing member 6 is spatially fairly uniform and has little temporal variation. There is no need to adjust the temperature. As a result, it is also possible to employ a three-stage valve that sets the heating power to “high fire”, “medium fire”, and “low fire”. In this case, start up with high heat and cook after starting up with medium heat. And energy saving can be achieved by reducing the heat during idle time. In order to prevent accidents due to the disappearance of gas, a safety means such as disposing the thermocouple appropriately in the meat cooking apparatus and automatically stopping the gas when the gas disappears is necessary.

  And when the above-mentioned heating power adjustment is a three-stage type, it becomes easy to make cooking manual, and there is an effect that cooks with little experience can be employed. In the meat cooking device according to the present invention, the temperature of the heat storage means 3 is made uniform and constant, the radiation of heat from the heat storage means 3 is made constant, and the temperature of the atmosphere around the meat N is made constant, and the meat placing member The heating condition by heat conduction from 6 is constant, and the heating condition by convection is also constant. As a result, if the type, size, and shape of the meat are the same, the internal temperature of the meat changes almost similarly every time. Therefore, by manualizing the required heating time in a tabular format for each type, size, shape, and finish of meat, anyone who cooks can quickly cook the meat as requested by the customer without failure. it can. As already mentioned, the manual does not have to be in paper format, and can be realized as program data in an embedded microcomputer.

  For example, the time required for the inside to become a rare medium welder is the same every time. Therefore, for each combination of meat thickness (for example, 15 mm, 20 mm,...) And meat weight (for example, 150 g, 200 g,...), Etc. It means that it can be created. By using this table, the meat N can be cooked in the same manner regardless of whether the cook is an expert or an unskilled person.

  FIG. 9A is an infrared photographic image showing the temperature distribution of the meat placing member 6 of the meat cooking apparatus not provided with the above-described net-blocking plate 5, and FIG. It is an infrared photographic image which shows the temperature distribution of the meat mounting member 6 of the meat cooking apparatus which concerns. As can be seen from FIG. 9 (a), when there is no screen-blocking plate, there is a remarkable high-temperature part (blacked part in the figure) in the center, and the range of the high-temperature part (cooking area A) where meat can be cooked Is too narrow. On the other hand, when there is the netting plate 5, as can be seen from (b), the high temperature portion (cooking area A) extends long and exhibits a substantially elliptical temperature distribution as a whole. This indicates that the temperature of the meat placing member 6 of the meat cooking apparatus according to the present invention is uniform as compared with the case where the net cover plate 5 is not provided.

  Moreover, in one Example of the meat cooking apparatus which provided the net-blocking board 5, in the case of gas consumption (24-36 kW), the temperature of the cooking area A of a cooking surface will be 390 degreeC or more in high heat 15-20 minutes. It was. The high fire was used only at the start. When medium heat is used, 300 to 340 ° C is maintained. When it was set to low heat, 260-290 degreeC was maintained (in the case of LPG).

  On the other hand, when there is no heat shielding plate 8, the temperatures of the upper, middle, and lower portions of the front surface of the same type of meat cooking apparatus were “100 to 200 ° C.”, “70 to 80 ° C.”, and “50 to 60 ° C.”, respectively. However, the temperature at the corresponding position when the heat shielding plate 8 was provided was as low as “50 to 70 ° C.”, “50 to 60 ° C.”, and “40 to 50 ° C.”, respectively.

  If Japanese lava fragments are used as the heat storage means 3, the cause has not been investigated yet, but far-infrared rays are generated, and the meat is “juicy” and the surface is “crisp”. There was a cook to do.

  Although the meat cooking apparatus according to the present invention has been described in detail above, the application target of the present invention is not limited to the one illustrated in the drawings, and can be implemented as an apparatus of another form with the same technical idea. Needless to say.

  The meat cooking apparatus according to the present invention can be suitably used as a cooking apparatus for meat dishes in the restaurant industry, particularly in franchise chains for the purpose of providing inexpensively a desired amount of meat dishes of customers.
